Technical field
The utility model relates to a kind of environmental protection cleaner---and work function cathode pulse deduster is hanged down in grid-control.
Background technology
At present, the domestic environmental protection cleaner that is used for elimination of dust contamination, tradition is used electrostatic precipitator, and this equipment efficiency of dust collection is higher, but the high-voltage DC power supply power consumption of using is big.Be in the corona discharge state during electrostatic precipitator work, easily produce the arc light punch-through.For keeping the critical condition of corona discharge, to the power requirement height, anode and cathode is apart from the required precision height.This deduster pole plate is densely distributed, and cost is very high.The Chinese utility model patent 0125123917 magnetic control electrostatic precipitator of my application and ZL02274086.4 double-electric magnetic control Pulse Electric deduster has only reduced electric cleaner from charged particle dust angle of stressed deflection magnetic field cost have improved efficiency of dust collection.But on charged mechanism still is the corona discharge pattern of electrostatic precipitator, and pulse voltage is to be added between the anode and cathode, and power supply is a high-voltage pulse power source.
Summary of the invention
The purpose of this utility model is for administering dust pollution, be used for desulfurization and dedusting, provide a kind of grid-control to hang down work function cathode pulse deduster, its concrete solution is to adopt low work function negative electrode, the mechanism of field emission makes deduster cathode emission electronics, that decides electronics between the cathode grid under the control of grid has or does not have, the corona discharge that has solved electrostatic precipitator is improved to field-causing electron emission discharge, high-voltage pulse is improved to the pulse current between action of low-voltage pulse control grid formation high-voltage anode and the negative electrode, and the distance of negative electrode and anode is broadened by narrow.
Work function cathode pulse electric cleaner content Description is hanged down in the utility model grid-control
Work function cathode pulse electric cleaner is hanged down in the utility model grid-control, kicker magnet, shell, air intake vent, air outlet, charged control of dust one Room, charged control of dust two Room by: negative electrode, excitation anode, control grid, intensifying ring, anode, polymerization expansion chamber, band magnetic gap are formed, and it is characterized in that: in charged control of dust one Room and the charged control of dust two indoor anodes that distributing, intensifying ring, control grid, excitation anode and negative electrode; Kicker magnet by the band magnetic gap between charged control of dust one Room and charged control of dust two Room communicates, at charged control of dust one Room and the charged control of dust two chamber interior three kinds of electrodes that distributing, be negative electrode, control grid, anode, or at charged control of dust one Room and charged control of dust two chamber interior distributing two kinds of electrodes, i.e. negative electrode and anode; Negative electrode is to be made by low effusion cold-cathode material, in the outer setting of negative electrode excitation anode, excitation anode connects positive potential; Anode excites a large amount of electronics under the effect of excitation anode and cathode electric field; At the outer netted control grid that is with of excitation anode, the height of control gate electrode potential determines having or not of electronics; At the outer setting intensifying ring of control grid, the electronics accelerated motion under the intensifying ring effect from controlling grid and crossing the control grid obtains very high energy, and the electronics that is accelerated is the anode diffusive migration under the effect of positive plate.
Power supply is that anode adopts direct current (or pulse) high voltage supply, and accelerating anode adopts the sub-high pressure power supply, and the control grid adopts pulse power power supply, and the emission anode adopts the pulse power or low-voltage dc power supply (cathode potential is a zero potential).
In working order down, electric field between negative electrode and the excitation anode is enough to make negative electrode to produce pop-up, therefore in the space of negative electrode and excitation anode, formed electron cloud, if the control grid is in electronegative potential, then electronics can not be crossed the control grid, when the control grid be in high potential then electronics cross the control grid, anode motion under the accelerating anode effect.Therefore the electric current that flows to anode is a pulse current off and on.
When the anode no current, powder dust particle becomes polar particle under electric field action, and when anode had electric current, polar particle was by charged, and lotus is with the pole plate motion that faces south of the particle of negative electrical charge, and is caught by positive plate.
The utility model is to adopt electron field emission, and electrons emitted is moved under electric field action and diffusion, has overcome the not high phenomenon that causes efficiency of dust collection to descend of pole span precision, and anode voltage can reduce significantly than electrostatic precipitator, and pole span can be widened.Therefore the utility model is in the pulsed operation state, energy savings significantly.It can be used for the dust dedusting of high specific resistance.The high pressure of intensifying ring and anode quickens electronics, obtains high energy electron, and the utility model can be used for desulfurization and dedusting.
